WATSON SANFORD, OF BROOKLYN, NEW YORK.

Letters Patent No. 89,693, dated May 4, 1869.

JACKET FDR PIRE-PLACE-HEATERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that I, WATSON SANFORD, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and improved Method of J acketing for Fire-Place-Heaters and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing, and to the figures and letters thereon.

Of these drawings- Figure 1 is a front elevation of the improved jacket;

Figure 2 is a plan view, showing the dome portion and operation of the valve;

Figure 3 is a vertical cross-section, at the line A-a, of fig. 2; and

Figure 4 is a vertical longitudinal section, at the line B-b, fig. 2.

The modes of jacketing heretofore in use have been quite defective, by reason of their being constructed in such a manner that the products of combustion were retarded in their ascent to the hot-air pipe, and in the proper radiation from them ofcaloric, into the I apartment wherein the furnace or stove is situated.

My improvement, therefore, consists in an improved construction of the exterior jacket, composed of a combined semicircular back and dome-top, as hereinafter described; also, in an improved arrangement of valve, attached thereto.

Having reference to the figures or drawings, the same part in each of which is similarly lettereda is the base portion of the jacket, constructed about three-fourths of the whole height of the jacket, in a semicircular shape.

I) is the upper portion of the jacket, constructed in a. dome-shape, and attached to the lower portion by any convenient means, such as screw-bolts and nuts or rivets.

Both those portions can be made of two or more v point c. This handle, when the valve is closed, isnot 1 in the way, as seen by red lines in fig. 2. When open, the handle can be swung back out of the way, as seen by dotted lines in the same figure.

It will be seen that with my jacket the products of combustion have no angles, corners, 'or pockets, in

their course up to the hot-air pipe, and when they are thrown into the room, by reason of the closing of the valve leading t6 the hot-air pipe, this construction tends to radiate them better.

0 tatm.

1. Constructing the exterior jacket of a fire-place-- heater in a combined semicircular back and dome-top, substantially as shown and for the purposes described.

2. The arm d, attached to the valve e, when constructed, arranged, and operating substantially as described.
